Aimtec recommends a PCB layout with a large copper area for heat dissipation, and a minimum of 2 oz copper thickness. A thermal via array under the module can also improve heat dissipation.
Aimtec recommends using a soldering profile with a peak temperature of 240°C to 250°C, and a soldering time of 3-5 seconds. A soldering iron with a temperature-controlled tip is recommended.
Aimtec recommends keeping the input voltage deviation within ±10% of the nominal input voltage to ensure reliable operation and to prevent damage to the module.
Aimtec recommends using external overcurrent protection (OCP) and overvoltage protection (OVP) circuits to prevent damage to the module. The OCP should be set to 1.5-2 times the maximum rated output current, and the OVP should be set to 1.1-1.2 times the maximum rated input voltage.
Aimtec recommends using a low-ESR ceramic capacitor with a value of 10-22 μF, and a voltage rating of 1.5-2 times the maximum rated input voltage.
